Lamp-burner



l UNITED STATES PATENT OFFICE.

LAMP-BURNER.

l SPECIFICATION forming part of Letters Patent No. 224,459, datedFebruary 10, 1880.

Application led October 8, 1879.

To all whom it may concern.-

Be it known that I, ORLANDO MERRILL, of Courtland, in the county ofLawrence and State of Alabama, have invented a new Improvement inLamp-Burners, of which the following is a specification.

' Figure l is a sectional elevation of the lampburner.

, Fig. 3 is an enlargedv plan view, partly in secof hinged half-tubesand their operation g mechanism with the wick-tubes made with openedges, so that the wick-tubes may receive wider and narrower wicks.

The base-plate A of thc burner has its middle part raised andslotted toreceiveV the wick-tube B.

Upon the outer part of the base-plate A are formed two cencentric seats,C D, to receive chimneys of di'erent sizes, which chimneys are held inplace by springs E, attached to the hase-plate A in suchl positions asto rest n against the outer surface ofthe smaller chimney and againstthe inner surface of the larger chimney, so thata smaller chimney andanarrower wick may be used when less light is required, and a largerchimney and a wider wick may be used when more light is required, thusavoiding the necessity of having two lamps or two burners for the samelamp.

To the lower side of the middle part of the base-plate A is attached acollar, F, having a screw-thread formed upon it to screw into the collarof the lamp.

The part of the wick-tube B above thebaseplate A is made with open sideedges, and is slightly tapered, as shown in dotted lines in Fig. 1.

To the base-plate A, at the side edges of the wick-tube B, are hingedthe lower ends of thel side edges of the two half-tubes G, which areFig. 2 is a plan view' of the burner.A

tapered upon their inner edges, as shown in Fig. l, so that when theupperends of the half-tubes Gr are moved inward the said halftubes, inconnection with the open-edged upper part of the wick-tube B, will forma narrow wick-tube. When the upper ends of the `half-tubes G are movedoutward the said halftubes G, in connection with the open-edged upperpart of the wick-tube B, form a wide wick-tube to receive a wide wick,so that differen t-sized wicks and dii'erent-sized chimneys may be usedwith the same burneryas more or less light is needed.

i Along the inner edges of the half-tubes Gr are formed grooves H, inwhich work pins l attached to a disk, J. The' dislI J is pivoted to astandard, K, attached to the base-plate A, and to the outer end of itspivot is attached a button, L, for convenience in operating it.

With this construction the half-tubes G may be adjusted to form a wideror a narrower wick-tube byturning the dislI J.

Any other suitable mechanism may be used for adjusting the half-tubes Gas may be desired or convenient.

The wick-tube is covered with a cone, M, in the usual way. The wick isadjusted within the wick-tube by spur-wheels N, attached to a rod, O, inthe usual way.-

Having thus described my Invention, what I claim as new, and desire tosecure by Letters Patent, is.

l. In lamp-burners, the combination, with the wick-tube B, made with'open edges, of`

the half-tubes G, hinged at their lower ends, substantially as hereinshown and described,

so that the completek wick-tube may be adjusted to receive wide ornarrow wicks, as set forth.

2. In lamp-burners, the combination, with the hinged half-tubes G, ofthe grooves H,

lpins l, and disk J, substantially as herein shown and described, foradjusting the halftubes G to -form wider or narrower wicktubes, as setforth.

ORLANDO MERRILL.
